Residential Filter Basics

Most homes use 1″ deep pleated filters changed every 60–90 days. If you have pets, allergies, or live in a wildfire region, consider MERV 11 or MERV 13. If your system has a media cabinet (Aprilaire, Honeywell, Trane EFC), you have a 4″ or 5″ filter that changes every 6–12 months.

20 years serving homes, facilities, and commercial customers. Filters from trusted manufacturers. Free shipping on orders over $50. Filter Fit Guarantee. Call 1-866-469-8556 with questions.
